Learning

Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Define spatial locality.

💡 Hint: It relates to how data is organized in the cache.

Question 2

Easy

What is temporal locality?

💡 Hint: Think of a loop where the same data is read multiple times.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does spatial locality imply in caching?

  • Access to random memory locations is common.
  • Data accesses are concentrated in nearby memory.
  • Only recently accessed data will be cached.

💡 Hint: Consider how data is organized in arrays.

Question 2

True or False: In a direct-mapped cache, multiple addresses can map to the same line, leading to cache misses.

  • True
  • False

💡 Hint: Think about how data locations are organized.

Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with designing a cache for a system that experiences rapid data access in bursts followed by periods of inactivity. Which replacement policy would you choose, and why?

💡 Hint: Consider which policy focuses on usage history.

Question 2

Given the following access pattern for memory addresses: 1, 2, 1, 3, 4, 2, 5, if implemented in a small 4-line direct-mapped cache, which addresses would likely cause conflicts?

💡 Hint: Calculate the cache lines for each address based on modulo operation.
